The Literary Agent's Role Has Shifted — But It Has Not Shrunk

The publishing landscape has changed substantially over the past two decades. Authors can now upload a manuscript to a global retail platform within hours, build readerships without institutional gatekeepers, and retain full creative and financial control over their work. Given all of that, a reasonable question follows: what does a literary agent still do that an author cannot do independently?

The answer depends almost entirely on which publishing path an author is pursuing — and what they are trying to achieve.

What Literary Agents Actually Do

For authors targeting the Big Five publishers — Penguin Random House, HarperCollins, Simon & Schuster, Hachette, and Macmillan — literary representation is not optional in most cases. These publishers do not accept unsolicited manuscripts from unrepresented authors. The agent functions as the first and primary point of access to editors at those houses.

Beyond access, agents negotiate contracts. A standard publishing contract runs between 20 and 50 pages and covers advances, royalty rates, subsidiary rights, reversion clauses, option clauses, and territorial rights, among other terms. Most authors sign only a handful of contracts in a career. Agents negotiate dozens or hundreds. That experience gap has direct financial consequences.

Agents also manage subsidiary rights — audio, translation, film, television, and serial rights — either in-house or through co-agents in other markets. For a book with international or multimedia potential, subsidiary rights income can match or exceed the original advance. Leaving those rights unmanaged, or ceding them entirely to a publisher, represents a measurable loss.

The Commission Structure and What It Signals

Literary agents in the United States and United Kingdom typically earn 15 percent on domestic sales and 20 percent on foreign sales, with no upfront fees. This commission model means the agent earns only when the author earns. It also means agents are selective — they take on projects they believe they can sell.

That selectivity functions as an informal quality signal to editors. When an agent submits a manuscript, it carries an implicit endorsement. Editors at major houses receive far more submissions than they can evaluate individually. Agented submissions receive priority.

Where the Agent Relationship Extends Beyond the Sale

The transaction does not end at the deal. Agents serve as long-term career advisors, helping authors evaluate whether to accept a particular offer, which editor at a house might be the best creative fit, and whether a book should go to auction or be placed through a pre-empt. They handle disputes between authors and publishers when they arise, and they track royalty statements for accuracy.

Some agents also provide developmental feedback before submission, though the degree varies widely by agent and agency. Authors should ask about this specifically during the query process rather than assuming it is included.

When an Agent Is Not the Right Move

For authors publishing in genres where small or independent presses dominate — certain poetry collections, regional nonfiction, academic titles, or experimental literary fiction — many publishers accept unagented submissions. In these cases, an entertainment lawyer can review contracts on a one-time basis without requiring the ongoing commission relationship an agent entails.

Self-publishing, hybrid publishing, and direct licensing arrangements also exist entirely outside the traditional agent-publisher model. Authors in these spaces do not require representation and may not benefit from it.

How to Approach the Query Process

Authors seeking representation submit a query letter — typically one page — along with sample pages and, for nonfiction, a proposal. Resources such as QueryTracker, Publishers Marketplace, and the individual agency websites provide submission guidelines, recent sales data, and agent wishlists.

Response times vary from two weeks to six months. Many agents operate on a no-response-means-no policy. Authors querying multiple agents simultaneously — which is standard practice — should track submissions carefully to avoid duplicate offers or missed responses.

The agent-author relationship, when functioning well, is a long-term professional partnership. Vetting an agent's recent sales, client list, and agency reputation before signing a representation agreement is standard due diligence, not skepticism.
